T0 ALL-WHOM IT MAY corvonnrv:

Be it known that we, DEWEY PHILLIPS, of Shaftsbury, in the county ofBennington, and State of Vermont, and WILLIAM REID, of West Arlington,in the county of Bennington, and State of Vermont, have invented-a newand useful Method of Securing the Heads in Seamless Kegs or Casks, orbottoms in tubs, bn'ckotaand other like articles; and we'do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being bad to the accompanying drawings making part..of this-specification, in which-.

Figure 1 is an elevation of a cask completed according to our improvedmethod; and

Figure 2, a section thereofrtaken in the plane of the axis of the cask.

Oursaid invention relates to a methodof securing the heads in seamlesskegs and c asks, or the bottoms in tubs, pails, and other like articlesthat are made by cutting cylindrical shells from .tolid blocks of wood.

Prior to our said invention the heads or. bottoms were put into suchseamless articles by making the heads or bottoms of a diameter a littlegreater than the inner diameter of the shell where the crozewas-formed,and then steaming the end of the shell to admit of stretching orexpanding jitsuificiently to permit the head or bottom to be inserted,relying upon the shrinkage of the wood afterwards to close around. andhold it. This method, however, was found to be so defective that itcould not be successfully introduced into practice. The

w-ood-,--after having been-so steamed-and expanded, was very liable toleak, and the head or bottom to drop out,

if exposed-to the drying influence of the atmos'phere without a liquidinside. According to our improved method we make the heads, a a, or thebottom, of less diameter than the inner diameter of the shell 1 at' thecraze, so that'they can be'readily introduced without stretching orexpanding the shell, and, whilst theheads (or bottoms) are held in placeby the application of pressure to the outside of the shell at or nearthe ends and all around, we compress the wood until the croze is broughtinto close contact with'the edges of the heads, and .beforethewood whichhas'been so compressed can expand, we drive on the hoops c c, .to holdthe wood in the compressed condition. The compression of the shell on tothe heads or bottoms may be effected by'means of a conicalmetal hoopdriven on to the vessehor by means of an expandingand contracting hoop,made to expand or contract by means of a screw-bolt orvwedge, or by anyother known means of concentric pressure; :do not, however, claim anymethod or machine for effecting said compression, but we prefer toeffect it by means of machinery invented by WILLIAM REID, one of theseapplicants,.subsequently to our invention herein described, for whichthe said REID filed an application forl etters Patent the 12th day ofMarch, 1866. After having been so compressed and held for a time, thewood has no disposition to expand and leave the heads (or bottom) evenwhen the hoops are taken off. And the compression of the wood closes thepores so completely as toprewent all leakage. By this method all kindsof'coopers work can be produced at. less cost and of a better qualitythan when made of staves. V We do not claim broadly, as of ourinvention, the insertion of heads or bottoms in the shells of seamlesscasks and other vessels, but what We do claim as our invention, anddesire to secure by Letters Patent, is-- The method herein described ofputting the heads or bottoms in seamless casks or other vessels, bymaking the heads or bottoms of a less diameterthan the inner diameter ofthe shells at the croze, and then compressing the ends of the shell intoclose contact therewith,- preparatory to putting on the hoops,substantially as described.
